Refractory ventricular tachycardia treated by a second session of stereotactic arrhythmia radioablation

PurposeStereotactic arrhythmia radioablation (STAR) is an effective treatment for refractory ventricular tachycardia (VT), but recurrences after STAR were recently published. Herein, we report two cases of successful re-irradiation of the arrhythmogenic substrate. CasesWe present two cases of re-irr...

Description
Summary:PurposeStereotactic arrhythmia radioablation (STAR) is an effective treatment for refractory ventricular tachycardia (VT), but recurrences after STAR were recently published. Herein, we report two cases of successful re-irradiation of the arrhythmogenic substrate. CasesWe present two cases of re-irradiation after recurrence of a previously treated VT with radioablation at a dose of 20 Gy. The VT exit was localized on the border zone of the irradiated volume, which responded positively to re-irradiation at follow-up. ConclusionThese two cases show the technical feasibility of re-irradiation to control recurrent VT after a first STAR.
